Blood clotting disorders are conditions that cause excessive clotting, limiting or blocking normal blood flow. If you have a blood clotting disorder, your blood may clot too easily or the clots may not dissolve normally and can break off and travel to other parts of the body.
During pregnancy, blood clotting disorders can pose serious risks to the mother and baby.
Understanding Your Risks
Blood clots during pregnancy are a leading cause of maternal death in the United States.
Pregnancy itself increases the risk of developing blood clots.
Your risk of developing blood clots during pregnancy is further increased by:
- Personal or family history of blood clots
- Genetic disorders that increase your tendency for excessive clotting
- Obesity
- Hypertension
- Smoking
- Cesarean delivery
- Multiple births
- Advanced maternal age
- Infection or other associated medical conditions
The Dangers of Blood Clots
Blood clots can be stationary and block blood flow (known as a thrombosis) or they can break loose and travel through the bloodstream to other parts of the body (known as an embolism).
In pregnant women, blood clots most often develop in the deep veins of the legs or pelvis, a dangerous condition known as deep vein thrombosis (DVT). If part of the clot breaks free, it can travel to the lungs, a life-threatening condition known as pulmonary embolism.
Much less commonly, blood clots can also travel through your bloodstream to other major organs, including the brain, causing a stroke, or the heart, causing a heart attack.
Blood clots are typically diagnosed through imaging tests, including ultrasound, CT scans and magnetic resonance imaging (MRI).
Treatment of Blood Clots during Pregnancy
Treatment depends on the woman’s condition, her history of blood clots and her pregnancy. In general, treatment may include:
- Specialized obstetric care
- Blood thinners that are considered safe during pregnancy
- Close monitoring for early detection and treatment of blood clots
- A multidisciplinary health care team that may include a hematologist (a specialist in treating blood disorders), an anesthesiologist experienced in pregnancies with clotting disorders, and a specialist in critical care medicine, if needed
- A carefully planned delivery
- Testing for inherited clotting disorders, if indicated
- Delivery at a state-of-the-art facility equipped to respond to emergencies during and after childbirth
